UV resin, also known as photosensitive resin, is an oligomer that can undergo rapid physical and chemical changes in a relatively short time after exposure to light, thereby cross-linking and curing
UV resin is a photosensitive resin with a relatively low molecular weight, and has reactive groups that can carry out UV, such as unsaturated double bonds or epoxy groups
UV resin is the base resin of UV coatings, which is compounded with photoinitiators, active diluents, and various additives to form UV coatings
UV coatings have the following advantages:
(1) Fast curing speed and high production efficiency;
(2) High energy utilization rate and energy saving;
(3) Low organic volatile matter (VOC), environmentally friendly;
(4) Can be coated with various substrates, such as paper, plastic, leather, metal, glass, ceramics, and so on;
UV resin is the largest component in UV coatings, and is the base resin in UV coatings. It generally has groups that can further react or polymerize under light conditions, such as carbon carbon double bonds, epoxy groups, etc. According to the type of solvent, UV resins can be divided into two categories: solvent based UV resins and waterborne UV resins. Solvent based resins do not contain hydrophilic groups and can only be dissolved in organic solvents, while waterborne resins contain more hydrophilic groups or segments, which can be emulsified in water, Dispersion or dissolution
Classification of UV resins:
Solvent based UV resin
The commonly used solvent based UV resins mainly include: UV unsaturated polyester, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV pure acrylic resin, UV epoxy resin, and UV organosilicon oligomers
Aqueous UV resin
Waterborne UV resins refer to UV resins that are soluble in water or can be dispersed in water. The molecules contain a certain amount of strong hydrophilic groups, such as carboxyl, hydroxyl, amino, ether, acylamino, etc., as well as unsaturated groups, such as acryloyl, methacryloyl, or allyl. Waterborne UV trees can be divided into three categories: lotion, water dispersible, and water-soluble. They mainly include three categories: waterborne polyurethane acrylate, waterborne epoxy acrylate, and waterborne polyester acrylate
The main application fields of UV resin: UV coatings, UV inks, UV adhesives, etc. Among them, UV coatings are the most widely used, including the following types of UV water-based coatings, UV powder coatings, UV leather coatings, UV optical fiber coatings, UV metal coatings, UV paper polishing coatings, UV plastic coatings, UV wood coatings
